Advice needed with overgrown apple yard – Reddit Post

Hello!

Long story short. I have 0 experience with apple trees. I have spent the past 5+years shoveling thousands and thousands of apples into the dump. I have the most stubborn parents, who refuse to cut the trees or do any sort of prevention, care for this issue. I have decided to take matters into my own hands. We have about 10 trees, some of them are higher than 10meters. They are all quite ole, between 20-40year old trees. They have so many branches it makes our garden dark and humid.

How can we have nice apple trees that don’t overproduce, as we throw away 98% of the apples. Something is telling me they are in a bad condition already. What should be done, how much can be done? Should all big branches be cut? Where should I start with? What shouldn’t be done?

I appreciate all advice and help given by you guys! Thanks a lot.
